I was driving my vehicle several days after having a routine oil change and the vehicle started to slow down. I took my car in to be checked out and was told that I need a new engine, the truck has a loss of power due to the stabilizing trak issue. After reading all the complaints online this seems to be a problem which needs to be addressed by chevy.

This started as I was driving down interstate at 65 MPH. Suddenly my traction control light on dash came on along with blinking check engine light. Also read stabilitrak off and service traction control in readout below. Immediately my truck lost power and decelerated so I immediately pulled off road as to not get ran over by traffic. Read manual said to turn off and restart. Did this and all was good for another mile then happened again on and off for last 12 miles before I could get home. Upon taking it to dealership today they came back saying nothing about these codes but that there was a misfire code and oil low?? So now I have got an oil change and fuel system cleaning. Upon asking about the initial problem I was told to drive it to see if it happens again. This is a major issue with apparently the whole truck platform at gm. This problem is posted all over internet with cars even shutting off and brakes locking up and the big problem is no dealership knows how to fix it. Charge people a bunch of money to fix numerous things they know will not fix issue. This should be a major recall on 2007- at least 2010 from what I can see from data that is out there. I will be selling my truck after this because I do not feel safe driving my kids in it. I'm die hard chevy guy who has a 2003 suburban with 400000+ miles on it with very little issues in all these years. Please make gm fix this problem.

My 2008 suburban started burning a tremendous amount of oil. Seems like I was continuously adding oil. Raised the issue with the dealer, who indicated it was a common problem but probably not worth the expense of fixing if I could keep checking the oil. This advice was also based on the fact that all my maintenance has been performed at this dealer, so they know the vehicle well. The last week in january was very busy and saw me driving about 100 miles a day. On thursday, about 30 miles from home, the check engine and traction control lights starting blinking, the car lost power, and the engine began running rough. This was on a very busy highway (u.s. Route 50 near annapolis) during rush hour. This created a dangerous situation. I was eventually able to get the car home. When I brought it to the dealer, they said the oil was dry (I had checked it the previous weekend), a lifter had broken, and a piston head was scored. The cost of work to fix would exceed the cost of a new engine. I now have a new engine, the cost of which was not in my budget. This experience reflects what has been have reported frequently on automobile related web sites.. Given that this is a design flaw, chevrolet should be covering at least part of this fix.
